HAY-CARRIER.

sPEoIFIcATIoN forming part of Lettere Patent Ne. 525,425, aeteeiseptember 4, v1894..

Application tiled May 19,1894. n

have invented a new and useful Improvement v 1n Hay-Carriers, of whichthe following is a specification. e

This invention relates to carriers in which a brake or clutch is used togrip or catch and hold the hoisting rope where it passes over' thesheaves in the carrier frame, and thus prevent the load from droppingdown from the 'carrier as it traverses the track; and it consists ofimproved means for releasing this brake or clutch from the rope, and inholding 1t released while the tackle is being lowered from or elevatedto the carrier.

It further consists of certain combinations and arrangements of partsset forth in the following specification and claims and shown in theaccompanying drawings. v -Y In the drawings Figure l is a side elevationof a carrier embodying my invention, the front side of ythe' carrierframe being removed to give a better view of the working parts. Fig. 2is a vertical section drawn on the line of Fig. 1. Fig. 3 is ahorizontal section drawn on the line Z, Z, of Fig. 1. Figs. et and 5 areside elevations of modified forms of carriers embodying my invention,the front sides of the carrier frames being removed to give 'a betterview of the working parts.

Fig. l shows a carrier A, mounted in the usual way upon a track B, whichmay be constructed in any suitable manner. is provided with sheavesorropewheels C over which the hoisting rope D is passed, and in theloops of which pulley blocks E are hung, all inthe usual manner.

' A stop block F having inclined faces G and catch shoulders I-I, issecured to the upper edge of the track B.v

Brakes or clutch pawls I are pivoted in the carrier frame by means of abolt J, and are arranged to catch and hold the rope D upon the sheavesG.

K ie .e yoke having e. limited ver-tical ending movement in the frame ofthe carrier, its arms extending up by the track B. Rollers or wheels Lare mounted upon the upper ends of the arms of the yoke K and areadapted to run up on the inclined faces G and lift the yoke.

' these forks,

The carrier seriei No. 511,811. me model.)

The upper part ofthe yoke is passed through a portion a, of the carrierframe which is extended up to support it, while the lower end isprovided with a pair of downwardly projecting slotted forks M.

The bolt J upon which the clutch levers I are pivoted, is passed throughthe slots in so that the yoke K will be secu'relyy supported laterally,but will have free vertical movement in the frame of the carrier to theextent of the slot in its lower end.

Horizontal branches N are extended a short distance on each side of theyoke so as to be parallel with the clutches I. Links O are connected tothese branches and also to the clutches. It will be seen that by thismeans when the rollers L run up the incline facesGr and lift the yoke Kthe clutches I will also be lifted off the rope D, which will thenbefree to run over the sheaves C, and the tackle may be lowered for aload. l

In order to hold Vthe carrier stationary at the stop F and the clutchesreleasedfrom the rope while the load is being elevated, dogs P arepivoted atQ in a portion of the frame of the carrier which is extendedout to receive them. These dogs are adapted to engage shoulders R on theyoke K, and hold it in its elevated position, so that the rollersLmounted in the upper ends of the yoke cannot pass underthe shoulders Hor out of .the stop F in which case the carrier will be held from movingalong the track, and `the clutches I will be held released from therope.

Abail S is connected to the dogs P and when the' load is elevated thisbail will be lifted by the tackle so as to throw the dogsP out ofengagement with the yoke K, and permit it to drop down and pass out ofthe stop F so the carrier can move along the track. The clutches I willnow drop on the rope and grip it upon the sheaves C, so as to prevent'the tackle from running down from the carrier. Y

The carrier being returned to the stop F the rollers L will run up oneof the inclines G and lift the yoke K and the clutches Iconnected to it,so that the tackle will be allowed to descend, and at the same timethedogs P will ICO engage the shoulders R on lthe yoke K, and

hold the rollers L from passing outl `of the stop. rlhe operation may berepeated at will.

Itis evident that the carrier may be operated either way from the stopF, andthe c lutch pawls I being set in opposite directions will grip andhold the rope on both sides of the elevating tackle. It is not essentialhowever, that the details shown in Figs. l and 2 above described shallbe strictly adhered to. I consider this the preferable form but am awarethat several modifications may be made without departing from the scopeand spirit of my invention. Two of these modifications are shown inFigs. 4 and 5.

Fig. 4 represents a carrier A designed to operate in either directionupon the track and is substantially the same as that shown in Fig. 1,except that the clutch T is made in i one piece. It has a verticalmovement in the frame of the carrier, and is designed to drop on therope between the sheaves C and hold it in both directions. TheyokeU hasalower forked endwhich straddles the clutch T, and is connected to it bymeans of the bolt V passing through the slotted hole Y.

It is desirable to have a little slack in the connection between thelifting device and the clutch, because dilerent sized ropes may be usedin the carrier, and if the connection was rigid a large sized rope mightnot permit the yoke to descend low enough to pass the rollers out of thestop F nor permit them to enter it. This is amply provided for in thelink connection shown in Fig. l. In Fig. 5 a one way carrier A2, isshown having only one hinged clutch pawl l2, and a single lifting linkK2 connected to the clutch and passed up on one side of the track tothestop F. This will answer the same purpose as the yoke K.

The yoke passing up around both sides of the track is the` preferableplan but the form of lifting device shown in Fig. 5 is within the limitsof my invention. The stop may also be secured to the lower edge of thetrack, (as is commonly done) and the lifting device extended up onlysuiiciently to engage the stop located in that position, withoutexceeding the scope and spirit of the invention. It is preferablehowever, to place the stop on the upper edge of the track and extend thelifting device up around the track to engage the stop, as shown in thedrawings, because by so doing the hoisting tackle can be drawn up closertothe track and space will thereby be economized in the operation of thecarrier.

The tripping bail S shown in Figs. 1 and 4 is dispensed with in Fig. 5,and a combined dog and trip lever P2, is used instead. It is hinged tothe carrier frame at e, and is constructed to straddle the clutch pawlI2, the front side being cut away in the drawings.

The elevating tackle is adapted to lift the lower end P3 and throw theupper end P4 out of engagement with the shoulder Pt2 of the lifting linkK2. W'hen the lifting link is raised by the stop F, the weight of thelower end P3 will draw the end MP4, under the shoulder R2.

The roller L shown in Figs. 1 and 4, is also dispensed with, and anordinary horizontally projecting finger L2, is used to slide up theincline G and catch against the shoulder I-I of the stop F.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
